After looking fruitlessly for a good way to transport my dice other than a dice bag (which I always seem to lose!) and being unable to find a good necklace I could buy cheaply near me, I decided to man up and make one. It really wasn't that hard. The die is completely removable from the holder, so that you can still use it in D&D, or it can hold a spin-down die for Magic: The Gathering. Very useful, because for me, it's much harder to lose something on a chain. The removable die also makes it fairly easy if you want your die's colour to match the rest of your outfit, or you need a different type of die. These instructions are to make a D20 necklace, however they are easily adapted to fit other types of dice as well. For those not familiar with dice naming, D indicates its a die, and the number indicates how many sides it has. Saying "Pass me the D20!" is a lot easier than saying "Pass me the icosahedron!", Especially when you really need to heal, and someone's rolling the die for fun.
Step 1: Supplies
To be able to make the dice jewellery you will need: Aluminum Wire (I bought mine at Canadian Tire for about $18), Scissors, Needle-nosed pliers, Large pen (Or other medium sized cylindrical object), Small chopstick (or other small sized cylindrical object -chopsticks are just what was convenient for me), Super glue (Or maybe you'll have better luck soldering than I did), and of course - dice ($1 each at my local gaming store)
Step 2: Starting the shape!
First the wire will need to be cut. I suggest taking off a larger chunk to begin with, much much more than you expect to use. It's easier to remove more at once because otherwise you risk the wire unwinding like crazy every time you need to grab more. Next a good sized portion of that wire should be cut off. I recommend AT LEAST about the length from the tip of your middle finger to your wrist (more if you have tiny hands). If it's the first time you're trying, I recommend using double just in case. Under-estimating the amount you need lives you with problems, over-estimating and you get a little bit more waste -but a lot less headaches. Next is wrapping the wire around the large pen. You want to leave a 2-3 cm gap between each wrap. just so it's not being wound too tightly.
Step 3: Forming the pendant - the tricky step
After removing the wire from the large pen, you apply gentle pressure to each size to increase the radius of the mini-circles. You also want to be pushing outwards at an angle, so that the middles both come closer together. This is harder to explain without looking at the picture, but what you're essentially doing is making a bendy wave that kind of looks like an M. This makes it easier for the die to fit in, and pop easily in and out of place. After the stretching is done, it's time to grab the D20. it's easiest to fit the wire around it at this point, that way you can adjust the sizing based on the individual die. You want to make sure you can pinch all of the wires together at one spot in the back, and that the die will not fall out if you shake it like that. After that you want to grab the wire with needle-nosed pliers where you were pinching, and give it a couple good turns. Be careful not to do too hard depending on your wire, or you may have snapping problems.
Step 4: Glue it in place!
The pliers will keep it somewhat in place, but I still recommend gluing it at this point. You could try soldering it, but I was having some difficulties and after a couple broken wires said "Glue it!". If you find a way please tell me, I'd be interested to learn! I used ZAP-A-GAP because it's what I had at home from model building. You'll want to be sure it dries clear, unless you plan on painting it after (duh). After removing the die, carefully apply it over top of the twisted wires, being careful not to get any on your hands (but we both know that won't happen), and leave it until it is completely dry.
Step 5: Chain holder (Is that what it's called?!)
After it was completely dry, I put the die back in the holder. The chopstick was used to shape the area that the chain was going to pass through. The chopstick was place at the base of the twist (please note I used a child's chopstick) and once again twisted with the pliers, and then glued.
Step 6: Thread the chain and.... TA-DA!
After the chain is thread, the necklace should be good to go! making more isn't hard, and it get's significantly easier each time. It's not that hard to master in less than an hour or two. Different dice require different shapes (such as the D4's to be earrings in the future) but after knowing the basics it's not that hard to figure out how to bend the right shape. Good luck! :D
